Monaco Integrates Mareterra Maritime Eco-District into National Thalassothermal Energy Loop at EVER Summit

H.S.H. Prince Albert II Showcases Mareterra Eco-District as Global Model for Maritime Urbanism

MONTE CARLO, Monaco — Positioning the Principality of Monaco at the vanguard of sustainable coastal engineering and ecological transition, His Serene Highness Prince Albert II and the Prince’s Government (*Gouvernement Princier*) have advanced comprehensive operational integration for Mareterra, Monaco’s groundbreaking six-hectare maritime eco-district. Reclaiming land from the Mediterranean Sea with state-of-the-art environmental protections, the monumental €2 billion eco-quarter expands the sovereign territory by three percent while establishing a pedestrian-first sanctuary engineered around renewable energy.

Designed in collaboration with world-renowned architects Renzo Piano and Denis Valode, Mareterra harmoniously merges ultra-efficient luxury residential architecture with expansive public infrastructure, highlighted by the Esplanade et Promenade Prince Jacques, the waterfront Place Princesse Gabriella, a 16-berth marina, and lush Mediterranean pine forests that shade public pedestrian walkways.

Seawater Heat Pumps and AI-Optimized Smart Grids Spotlighted at 21st EVER Monaco Forum

Monaco's technological leadership in urban decarbonization took center stage at the 21st EVER Monaco summit, hosted at the One Monte-Carlo conference center under the high patronage of Prince Albert II:

• Thalassothermal Heating and Cooling Loop: Harnessing deep Mediterranean seawater heat exchangers (*boucle thalassothermique*) to supply 100 percent of Mareterra's interior thermal regulation without consuming fossil fuels.
• 4,500 Square Metres of Solar Photovoltaics: Integrating high-efficiency solar panels seamlessly onto residential rooftops and public canopies, feeding clean electricity directly into the national smart grid.
• AI-Driven Energy Optimization: Partnering with Monegasque environmental researchers to deploy artificial intelligence algorithms that predictively balance HVAC loads, electric vehicle fast chargers, and domestic water heating.
• Marine Biodiversity Sanctuary: Fabricating artificial coastal reefs and submerged caissons designed with textured bio-concrete, actively repopulating native Mediterranean flora and Posidonia oceanica seagrass beds.

National Energy Transition Pact and Long-Term Mediterranean Decarbonization

Mareterra’s energy architecture directly advances Monaco's statutory National Energy Transition Pact, which mandates a 55 percent reduction in greenhouse gas emissions by 2030 and complete carbon neutrality by 2050. Connected to the wider Principality through the MonaBike electric bike-sharing network and Compagnie des Autobus de Monaco (CAM) zero-emission electric shuttles, the district demonstrates that high-density alpine-maritime urban development can coexist in total harmony with coastal ecological preservation.

By pairing world-class architectural beauty with cutting-edge marine energy science, Monaco proves how sovereign commitment to ecological stewardship delivers enduring economic prestige and environmental sustainability.
